Answer:
y-axis : B) (-4, -3)
y = 1 : E) (4, 5)
y = x : C) (-3, 4)
y = -x : D) (3, -4)
x-axis : A) (4, 3)
Step-by-step explanation:
y-axis : B) (-4, -3)
y = 1 : E) (4, 5)
y = x : C) (-3, 4)
y = -x : D) (3, -4)
x-axis : A) (4, 3)
Reflect in y-axis: change sign of x-coordinate only
Reflect in x-axis: change sign of y-coordinate only
Reflect in y = 1 : change sign of y-coordinate and add 2 units
Reflect in y = x : swap numerical values of x and y coordinates AND change signs
Reflect in y = -x : swap numerical values of x and y coordinates (keep original +/- signs)
Answer:
x is 100 and y is 40
Step-by-step explanation:
First make 500 into a number where it can be divisable by 3. 5x40=200
500-200=300, 300 divided by 3 equals 100
x=100
y=40
Answer
40
The formula to determine the area of the right triangle is a*b/2
First, let’s input the numbers into the formula.
16*5/2
Now we need to solve.
16*5= 80
80/2= 40
Therefore, the answer would be 40.
<u><em>Answer:</em></u>
Jenna did 16 regular haircuts
Jenna did 8 haircuts with coloring
<u><em>Explanation:</em></u>
Assume that the number of regular haircuts is x and the number of haircuts plus coloring is y
<u>We are given that:</u>
<u>1- Jenna did a total of 24 clients, this means that:</u>
x + y = 24
This can be rewritten as:
x = 24 - y ...............> equation I
<u>2- regular haircuts cost $25, haircuts plus coloring cost $42 and she earned a total of $736. This means that:</u>
25x + 42y = 736 ..........> equation II
<u>Substitute with equation I in equation II and solve for y as follows:</u>
25x + 42y = 736
25(24-y) + 42y = 736
600 - 25y + 42y = 736
17y = 136
y = 8
<u>Substitute with y in equation I to get x as follows:</u>
x = 24 - y
x = 24 - 8
x = 16
<u>Based on the above:</u>
Jenna did 16 regular haircuts
Jenna did 8 haircuts with coloring
Hope this helps :)
Answer:
b = 55°
c = 35°
Step-by-step explanation:
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
